Which countries in europe have great opportunities for investments? and in what field?

Which countries in europe (mainly eastern europe)have great investments opportunities?and in what field?where can i get a contact to those places?many thanks!!!
Answer
There are some good opportunities in real estate, in the countries close to the mediterranean. stock markets in eastern europe still have some bargains, although less easy to find than they used to be. if you wanna go down that route, the best way in is to invest in an oeic (mutual fund). finally, there are some opportunities in bond and interest rate markets for those countries expected to join the euro (ie: not turkey).
